Location: As an indoor plant, provide the plant with bright light such as a well lit window. In the summer the plant can be moved with care to a warm, lightly shaded spot.
Soils: An acid soil is a must for miracle fruit. They prefer a soil acidity of pH 4.5 to 5.8. This can be achieved by planting in equal parts Canadian acid peat and pine bark. Also peat and perlite mixes are said to give excellent result. In the basic soils of California, the plants slowly die back until virtually only the stems remain. Allow the roots of the plant to fill the container before transplanting into a larger one.

Irrigation: Be sure that the soil is well draining as the plants do not like to sit in wet soils. Coming from a tropical climate they need highly humid conditions. When indoors, especially during the winter months, a small clear plastic bag put around the plant and supported by wood or a wire frame is helpful in maintaining humidity. Also, placing the plant container on a tray with stones on the bottom and filled with water to the top of the stones will add humidity to the local area. Misting the leaves with good water also helps.

Fertilization: Use a water soluble fertilizer such as Miracid and follow the label directions. Use sparingly with frequency dependent on the growing season, fertilizing more frequently during the summer months.

Pruning: In general, there is no need to prune the miracle fruit plant.

Propagation: Propagation of miracle fruit is usually either by seed or cuttings. As the seed viability is short, plant the cleaned seed immediately just below the soil line When shipping cleaned seed for others to plant, package in a small plastic bag and enclose a slightly moistened toweling. Seed that are allowed to dry can be shipped for at least two weeks but rapidly loose their viability.

Pests and diseases: Watch for mealybugs, spider mites and other indoor potted plant pests. Waterlogged plant will succumb to root rot.

Commercial Potential: The plant is not important as a food crop. Attempts to exploit the striking effect on perception of sour flavors in development of artificial sweeteners have not been successful but are continuing.
